Fatjoe, where is the evidence for that please? All that i could find is that red meat, no matter how its cooked, eaten to excess (more than 500 g cooked or 700 g if weighed raw per week) MIGHT contribute to colon cancer.
here is the most reliable source that I have found and even then i think its still a bit sweeping in its statements.

Even the best chef cannot produce wonderful results with poor ingredients.
I agree about pan not grill. get the pan very hot, make sure that the steak isn't dripping with liquid but don't do more than dab it and whack it on.
